Predicted and Actual Returns

From the equation presented on the U.S. market valuation page,

Investment Return (%) = Dividend Yield (%) + Business Growth (%) + (Re/Rb)(1/T)-1

We can compute the predicted and actual returns of the UK stock market over a given time period, T. In the calculation, we set T to equal eight years, the approximate length of a full economic cycle. The calculated results are presented in the chart below. The green line indicates the expected, or predicted return if the market ratio trends near the recent 20 years average ratio of 113.73% over the next eight years.

The blue line indicates the actual, annualized return of the UK stock market over eight years. We use “FTSE 100 index” to do the actual return calculation. We can see the calculations largely predicted the trend in the stock market as the blue line is closely parallel to the green line.

Conclusion

The stock market of UK is expected to return 8.3% a year for the coming years. This is from the contribution of economic growth in local current prices: 3.29%, Dividend Yield: 2.89% and valuation reverse to the mean 2.08%.
